Buried Utility Pipeline Mapping based on Street Survey and Ground Penetrating Radar

In the UK and many other countries, underground networks are used to deliver a range of services to households and industries. Maintaining and upgrading these networks are major undertakings. In order to avoid unnecessary holes dug in wrong places, prior to invasive works it is normally required that excavators should request and obtain record information from all relevant utilities to identify what is buried where. However, the mapping information supplied by utility companies is often of limited use as asset records are usually inaccurate and incomplete. Thus a street survey is often conducted using sensor devices, such as ground penetrating radar (GPR). However, these are costly, and forming a complete picture combining the expectation of the map and the sensor data is an expert task. This paper will investigate an algorithm for utility pipeline mapping based on street survey and GPR data.
